WALL MOUNTING THE RTi28 AND RTi38 BOOKSHELF LOUDSPEAKERS
The RTi Series Bookshelf Loudspeakers feature a rear firing Power Port which doubles as a wall
mounting bracket. Follow the steps below to safely wall mount these speakers. Wall mounting
requires basic skills in with tools such as a drill and a screwdriver. If you are in doubt that you
possess the necessary skills or tools, consult your Polk Audio dealer, or a professional installer.
• Make sure the material on which you plan to mount the speakers (plaster, drywall, paneling,
stone, etc.) can support the weight of the speakers (RT
i28=approx 15lbs/6.8kg ea.,
RT
i23=approx 20lbs/9.1kg ea).
• Make sure the locations you select do not conceal electrical wiring or plumbing.
• Prior to installation, hold the speaker in the chosen location to make sure it safely
clears obstacles such as ceiling, adjacent walls, corners, beams, lighting fixtures and
door/window frames.
• Using the keyhole slot in the bracket template (included), mark the installation location of the
keyhole slot with a pencil [figure 8]. Orient the template so that the small end of the keyhole
slot facing “up” according to the direction of installation.
• If you are certain that there is a stud behind the wall surface, drive #10 screws (not included)
through the wall and into the stud [figure 9a].
• If there is no stud behind the wall at the chosen location, install #10 wall anchors
(not
supplied)
into the wall by following the wall-anchor-manufacturer’s instructions. Always use
two wall anchors and two screws per speaker
[figure 9b].
• For masonry walls, use a masonry drill bit and #10 masonry anchor and screw
(not included).
•Tighten screws into stud or wall anchors, leaving screw heads protruding 1/16” (1.6mm).
• Line up the keyhole slots on the back of the Power Port so that the screw heads pass through
the large center hole of the slots.
• Let the speaker and slide straight down, allowing the screw head to slip behind the smaller end
of the keyhole slot
[figure 10].
•Tug gently on the speaker to make certain that the screws and bracket are properly aligned and
that the wall anchors are secure.
• If the bracket is not held snug against the wall by the screw heads, remove the speaker from
the wall, drive the screws in a little further and then remount the speaker.
SAFE LIMITS OF OPERATION
Your Polk loudspeakers are made with the highest quality materials for years of trouble-free
performance. However, damage to loudspeakers can occur when an amplifier, regardless of its
wattage, is made to play at higher listening levels than its power can clearly produce (usually
beyond the “1 to 2 o'clock” position on the volume control). This results in very high levels of
audible distortion, originating in the amplifier, that can add a harsh, gritty sound to music.
Contrary to popular belief, a speaker is more likely to be damaged by trying to get too much
volume from a low-powered amp or receiver than from a high powered one.
TAKING CARE OF YOUR RTi SERIES LOUDSPEAKERS [figure 11]
Your new RTi Loudspeakers are finished in natural wood veneer. Clean and dust the veneer
with a damp cloth only. Do not use furniture polish on the veneer. Carefully vacuum the grilles
to remove dust.
